ADR 2022-12-05: Adding labels to our resources

Date: 2022-12-05

Status: Superceded ¹

Context

users need to provide us with logs so that we can help support and troubleshoot their issues. We need a way for our users to filter and retrieve the logs we need.

Proposal

A good start would be a catch-all label to get all logs that are ARC-related: one of the recommended labels is app.kubernetes.io/part-of and we can set that for all ARC components to be actions-runner-controller.

Assuming standard logging that would allow us to get all ARC logs by running

kubectl logs -l 'app.kubernetes.io/part-of=actions-runner-controller'

which would be very useful for development to begin with.

The proposal is to add these sets of labels to the pods ARC creates:

controller-manager

Labels to be set by the Helm chart:

metadata:
  labels:
    app.kubernetes.io/part-of: actions-runner-controller
    app.kubernetes.io/component: controller-manager
    app.kubernetes.io/version: "x.x.x"

Listener

Labels to be set by controller at creation:

metadata:
  labels:
    app.kubernetes.io/part-of: actions-runner-controller
    app.kubernetes.io/component: runner-scale-set-listener
    app.kubernetes.io/version: "x.x.x"
    actions.github.com/scale-set-name: scale-set-name # this corresponds to metadata.name as set for AutoscalingRunnerSet

    # the following labels are to be extracted by the config URL
    actions.github.com/enterprise: enterprise
    actions.github.com/organization: organization
    actions.github.com/repository: repository

Runner

Labels to be set by controller at creation:

metadata:
  labels:
    app.kubernetes.io/part-of: actions-runner-controller
    app.kubernetes.io/component: runner
    app.kubernetes.io/version: "x.x.x"
    actions.github.com/scale-set-name: scale-set-name # this corresponds to metadata.name as set for AutoscalingRunnerSet
    actions.github.com/runner-name: runner-name
    actions.github.com/runner-group-name: runner-group-name

    # the following labels are to be extracted by the config URL
    actions.github.com/enterprise: enterprise
    actions.github.com/organization: organization
    actions.github.com/repository: repository

This would allow us to ask users:

Can you please send us the logs coming from pods labelled 'app.kubernetes.io/part-of=actions-runner-controller'?

Or for example if they're having problems specifically with runners:

Can you please send us the logs coming from pods labelled 'app.kubernetes.io/component=runner'?

This way users don't have to understand ARC moving parts but we still have a way to target them specifically if we need to.
